According to the largest meta-analysis of its kind, sperm counts around the world declined by more than 50 percent, to 47 million sperm per mL, between 1973 and 2013, and continue to dwindle

Endocrine disrupting chemicals have undoubtedly contributed to the dramatic decline in reproductive health among men. Excessive microwave radiation from wireless technologies,obesity and inactivityalso play a significant role
